CIP metal actuated deck insert

Abstract

A cast-in-place concrete anchor assembly for installation in or on a metal decking form. The assembly incudes an anchor housing with shaft extending from a flange. The flange includes a locking member that may take the form of a female thread. The anchor housing further including an anchor sleeve or spacer. The anchor assembly also including an anchor support with a receptacle for receiving the anchor sleeve and a shaft of the anchor housing. The anchor support further includes a radial expansion member for flexing outward to trap the anchor assembly to a support such as an edge of a hole in concrete metal decking.

The invention claimed is: 
     
         1 . A cast-in-place concrete anchor assembly connectable to a hole in concrete metal decking, the assembly for supporting an external load from a concrete structure, the assembly comprising:
 an anchor housing, the anchor housing including a load bearing flange and a shaft extending therefrom and including a connection member from which an external load may be connected to the cast-in-place concrete anchor; an anchor support including a receptacle for telescopically receiving the shaft of the anchor housing therein, the anchor support further including a base support flange and a radial expansion member, the shaft engaging the radial expansion member forcing it radially outward past the hole, trapping the hole between the base support flange and the radial expansion member.   
     
     
         2 . The cast-in-place concrete anchor of  claim 1 , wherein the shaft is tubular or cylindrical. 
     
     
         3 . The cast-in-place concrete anchor of  claim 1 , wherein the anchor housing is made of metal. 
     
     
         4 . The cast-in-place concrete anchor of  claim 1 , wherein the anchor housing is made of metal and the anchor support is made of a non-metallic material. 
     
     
         5 . The cast-in-place concrete anchor of  claim 2 , wherein the anchor housing is made of metal and the anchor support is made of a plastic. 
     
     
         6 . The cast-in-place concrete anchor of  claim 1 , wherein the radial expansion member includes at least one flexible finger, the at least one flexible finger being flexible radially outward in response to actuation by the anchor housing to trap the metal decking. 
     
     
         7 . The cast-in-place concrete anchor of  claim 6 , wherein the flexible finger is cantilevered and has a fixed end and a free end and the free end flexes radially outward. 
     
     
         8 . The cast-in-place concrete anchor of  claim 1 , wherein the radial expansion member includes a ramped surface that is inclined inward toward a central axis of the anchor. 
     
     
         9 . The cast-in-place concrete anchor of  claim 8 , wherein the incline toward the central axis is in a direction away from the base support flange. 
     
     
         10 . The cast-in-place concrete anchor of  claim 1 , wherein the radial expansion member flexes by means of an elastic or flexible material.
